Continuity mistake: In the scene where Ben is teaching Andie how to ride a motorcycle Andie's clothes change. At the start she is wearing a white top and black trousers which change to a pair of jeans. The jeans then change back to a pair of black trousers again at the end of the scene. (01:18:33)
Continuity mistake: When Andie runs out of the party and Benjamin follows her into the street, in the front shots of her face there is a strand of hair blown across her chin, but in the side shots there is no hair. (01:39:30)
Factual error: In the scene where Ben is bringing Andie back to his apartment after meeting her for the first time, you see the two helmets on tables in the living room, when obviously they just wore them on the motorcycle ride to the apartment. (00:23:45)
Continuity mistake: In the scene where Ben is teaching Andie to ride his motorcycle several people people can be seen on the boardwalk with them, which disappear in the aerial angle.
Continuity mistake: When Ben is talking to Tony and Thayer about him getting the account, he punches fists with each guy and when the camera angle changes to behind him, you see him punching fists with the second guy again.
Continuity mistake: When Ben asks Andie to go to the party, he tells her that he wants her to go as his girlfriend and she puts her right hand on his shoulder. The camera angle changes to a shot from behind and her hand is now on his chest.
Character mistake: In the very first scene in the film, the magazine covers are flashing up. There is an article called 'How to get a better bod in 5 days.' If you read the beginning of the article it says 'It Can Done.'
Continuity mistake: In the scene where Ben is putting on his shirt, he puts it on without buttoning it. The camera cuts to his friends for 2 seconds, then back to Ben. When the camera cuts back, Ben's shirt is buttoned and perfectly on. (00:06:45)
Continuity mistake: In the opening scene, there is a magazine article which reads, "... finally fall into place, only then will Tajikistan ..." The voice over - of the lady writing the article - says, "And only then will Tajikistan." (00:01:20)
Continuity mistake: When Andie first meets Ben she has her drink in her right hand but as the camera angle changes to a wider shot the drink is in her left hand so she can shake his hand with her right.
Continuity mistake: When Andie and Michelle are crashing at Michelle's place near the end of the movie, the cat on Andie's lap faces left, toward her head. When Michelle jumps up to answer the door in the very next shot, the cat is facing right before he jumps down. (01:42:33)
Revealing mistake: The first night Ben brings Andie home, he starts the music on the CD player, but no CDs are spinning at all. Yet, the music still plays. He also changes the track mid-scene, and still no CD is spinning.
Continuity mistake: When Ben and Andie are sitting on the couch, Andie has a wedding ring set on. When they go into the bedroom she doesn't.
Continuity mistake: In the final scene on the bridge, after Andie gets out of the taxi cab her hair is wavy and frizzy. Then in the next shot when she is standing next to the taxi cab just before the kiss her hair is different, it's curlier.
Factual error: The Knicks are supposedly playing at home for games 1, 3, and 7 of the NBA Finals during the course of the film. This is not possible for two reasons. First, games 1 and 3 are never played in the same location(either 2-3-2 or 2-2-1-1-1). Second, if the NBA Finals were to extend to 7 games, this would typically take place over two weeks and not the 10 day premise of the film.
Continuity mistake: In the scene where Ben is getting his shirt on in his office, in one shot he has one sleeve on. In the next shot, his shirt is totally on and buttoned to the top.
Other mistake: When Andie goes over to the diamond display (at the party) she isn't wearing any jewelry, and touches her ears a couple of times, demonstrating there's nothing on them. Later on she is seen wearing 'Isadorra' (the yellow diamond necklace) and a pair of matching earrings, which are certainly large and sparkly enough that they would have been visible if she was wearing them earlier. When security chases after Andie after she leaves, they only take back the necklace. I guess that the diamond earrings weren't that important. (01:39:30)
Continuity mistake: In the scene where Andie and Ben are looking at the photo album and Ben's mom calls for Andie, the phone keeps switching hands. First it's in her right hand, then her left, and back to her right by the end of the phone call.
Continuity mistake: When the ladies exit the meeting and are walking down the stairs after deciding that Andie will be writing the column on how to lose a guy, right before they meet the two executive ladies, Andie is seen starting to open up her bag to put her daytimer in. The camera angle changes to a wide shot and the daytimer is gone and the bag is closed.
Other mistake: In the scene where Spears is walking down the street and stops at the magazine stand to buy Composure Magazine, she hands the man a bill. The seller gives Spears her change without even looking at the money he was handed. How does he know what the exact change should be?
